SPECIFICATION forming part of Letters Patent No. 412,732, dated October15, 1889.

Application led January 3, 1889. A Serial No. 295,305. (No model.)

To all whom, it may concern.' l

Be it known that I, EZRA DEDERICK, of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented a new and usefulCar-Mover and I do hereby declare the following to be a full, clear,and' exact description of said invention, reference being had to theaccompanying drawings, and to the lettersV or figures of referencemarked thereon, which form a part of this speccation.

The object of my invention is to provide a device by which cars may notonly be started, but may be kept moving by and through a considerableleverage applied on the wheels causing them to rotate, which device isespecially useful lin moving freight trains up heavy grades. 4

My. device, so far as the parts of it which are directly attached to theordinary freight or passenger car are concerned, maybe operated directlyfrom the locomotive or by a special device constructed and attached to acar, which special means for operating is shown in the drawings, andwill be hereinafter described.

Figure 1 is avertical section showing a part of a freigh t-car and itsrunning-gear with my device attached thereto, and of a part of a secondcar with the special mechanism for operating my car-moving deviceattached thereto. Fig. 2 is a bottom or under side view of the same carsand mechanism shown in Fig. 1. Fig. 3 is an end view of the car A,having my device attached thereto. Fig. 4 is an enlarged view of acar-wheel and of that part of my devicewhich is attached directly to theaxle of the wheelsV and ot' other parts having close connectiontherewith. Fig. 5 is a vertical transverse section of a part of mydevice, (seen in Fig. 4,) the view being taken on line Y thereof,looking in the direction of the arrow. Fig. 6 is an edge elevation ofthe chain-pulley shown in Fig. 4. Fig. 7 is a vertical transversesection of the mechanism and car B, (shown in Fig. 2,) taken on line X Xthereof, and looking in the direction of the arrows. Fig. 8 is anelevation of the ratchetcase attached to the axle, showing thepeculiarly constructed lubricating cup'attached theretoin verticalsection, which I preferably use with my device. Fig. 9 is an elevation,

partin vertical section, of the same device shown in Fig. 8, taken atright angles thereto and looking in the direct-ion of the arrow in Fig.8.

The same letters and figures refer to like parts in all the views.

A and B are freight-cars of-the ordinary construction provided withwheels G C, rigid on axles D D, which axles are journaled in thevtruck-frame, consisting, as shown in the drawings, of theyokes E E, onwhich rest the cross-beams F F, on which are pivot-ed the bolsters G Gby means of king-bolts H H, the body of the cars being supported uponand made rigid to the bolsters G G. Two ratchetwheels 1 1 are affixedrigidly to an axle D, and a case 2, preferably made in two parts andbolted together on a horizontal line at 3 3, incloses each ratchet-wheeland is supported movably upon the axle. A pawl 4., pivoted in the case2, is adapted to engage with the teeth of the ratchet-wheel 1. A pulley5 is journaled in the upper part of the case 2, and a chain 6, securedat one end rigidly to the cross-beam F, runs around and upon the pulley5, being attached at its other extremity to an endwise-moving rod 7. Thecase 2 is pro.

vided with a gravity-weight 8, whereby the case is held yieldingly inthe upright position shown in Figs. 1 and 4.

The rod 7 is supported and moves endwise in brackets 10 10, affixed tothe under side of the car, and the rod 7 is continued and made up inpart of the chains 9 9, used as a part of the connecting device of themechanism for the purpose of giving iiexibility to it, and these rodsand chains are provided with means for connecting them together at theends of two cars. in a continuous line through the train,which means, asshown in the drawings, are the hooks, (seen at 11 11,) the cars in thedrawings being coupled by means of the links 12 12.

There are. two ratchet-'wheels 1 1 on each of one or more axles on eachcar,which ratchetwheels have their teeth turned in the same direction,and there are also two ratchetwheels on each of one or more axles of thesame car, the teeth of which ratchet-wheels are turned in the oppositedirection.

There are two rods 7 7 attached to each IOO ear, one of which rods isconnected by branching chains 6 6 to at least two cases 2 2, one ofwhich cases incloses a ratchet-wheel, the teeth of which are turned inone direction, and the other of which (2) incloses a ratchetwheel theteeth of which are turned in the opposite direction. These wheels beingcommonly placed one at one end of the car and the other at the other endof the car, and the gravity-weight8 of the respective cases being onopposite sides of the axles, and the tiltingchains 6 being passed aboutthe pulley 5 in opposite directions, so by the endwise movement of therod 7 the case at one end of the car is adapted to be tilted forward inone direction, while by the reverse endwise movcment of the rod 7 thecase at the other end of the car is adapted to be tilted forward in theother direction, the movement of the rod and corresponding tiltingforward of the case in each instance being adapted to throw the pawl 4into engagement with the ratchetwheel 1 and carry it forwardcorrespondingly, thereby rotating the wheel to a corresponding extent.

A small tripping-arm 13 is pivoted at one end in the under side of thepawl 4, and extends horizontally through an aperture in the case 2, andwhen the case is in an upright position bears at its other extremityagainst the end of a bracket 14, which bracket is rigid to thecross-beam F. When the case 2 is tilted forward by means of the chain 6,the tripping-arm 13 is carried away from engagement with the bracket 14,and the pawl 4 immediately drops into engagement with the teeth of theratchet-wheel 1 and remains in engagement therewith until the case 2 isbrought back into its upright position by the gravityweight S, when thetension on the chain 6 is released.

The rod 7, chains 6, and cases 2and 2",with their attached mechanism onone side of the car, are duplicated on the other side of the car, asshown, in the rod 7, case 2 and 2, and attached parts. l

Two levers 15 15-one at each end of the car-are centrally pivoted to theunder side of the car, and chains 16 16-one at each side-are connectedat their respective ends to the upper extremities of the respectiveadjoining cases2 2 and 2a and 2u. These chains 16 16 are a little slackwhen the cases 2 2 are tilted toward them to the limit of their movementin that direction, and the pawls 4 4 will then be out of engagement withthe ratchetwheels, as shown in Fig. 4, and in using this car-mover thisslack in the chain 16 16 is to be first taken up by drawing the rods 7 7forward until the chains 9 9 and 16 16 are taut, by means hereinafter tobe described, and then when either of the rods 7 or 7 is drawn forward,tilting the case forward farther on one side, the case o n the otherside will be correspondingly tilted rearwardly. When the rods 7 7 arereleased, so that the chains are slack again, the gravity-weights 8 8will tilt the cases 2 2 rearwardly, so as to throw the pawls 4 4 outofengagement with the ratchet-wheels 1 1.

It will be understood that by means of the mechanism already describedthrough a reciprocating endwise movement of the rods 7 and 7 alternatelya forced continuous rotary movelnent of the wheels is obtained by theforward tilting of the cases 2 and 2 alternately when running in onedirection, or by the forward tilting alternately of the cases 2n and 2awhen running in the other direction. Such an alternate reciprocatingmovement of the rods 7 and 7 may be obtained by connecting them directlywith the mechanism of the locomotive or by a similar mechanism,hereinafter to be described. The rods 7 and 7 are preferably enlarged orprovided with a sleeve for a bearing in those parts which pass throughthe brackets 1010. The pulley 5 is preferably made with a double groove,the inner one being narrow and intended t0 receive the edge ofalterna-telnks of the chain, while the sides of the other'alternatelinks of the chain rest on the bottom of the outer groove, as will beunderstood by reference to Fig. 6.

For lubricating the cases 2 2 about the axles on which they aresupported, I provide an oil or grease cup 17, affixed to or madeintegral with the case 2, having a false top 18, aixed at the rear edgeto the side of the cup and curving about the axle on its under side andterminating a little distance from the real cover 19, whereby theaperture 20 is left along the front upper edge of the false cover 18,through which the lubricant may come in contact with the axle when thecase is tilted forward, or opposite to which a sponge 21 may beinserted, which sponge will absorb a supply of oil from the 'cup whenthe case tilts forward, whereby the axle is kept constantly lubricated.The oil or lubricant may be introduced into the cup through an aperture22 in the rear part of the cup just beneath the false top 18. These cupsare provided on both sides of the cases 2, as shown in Fig. 9, though Ihave not introduced them in all the drawings, as the other parts areshown more conveniently without the presence of these oil-cups, and asthese oil-cups are not a requisite to the proper work of the othermechanism.

To properly operate the double set of devices on the respective axles,it is necessary to forcibly draw the rods 7 7 forward alternately, andfor this purpose these rods may be connected forward to proper mechanismon the locomotive, or may be operated by the device shown on the underside of car B in Figs. 1, 2, and 7. This mechanism has a movablecarriage 23, supported in ways 24 24, secured to the under side of thecar B. This carriage is adapted to move toward front and rear of the carto a very limited extent,which movement is provided for the purpose oftaking up any slack in the chains 9 9 and 16 16.

Secured ixedly to the carriage 23 are two steam cylinders 25 25 andtheir attached steam-chests 26 26, which steam-chests are each providedwith a piston adapted to reciprocate therein lengthwise of the cylinder,which pistons are each provided with a stem 27, these stemsat theirother extremities being respectively attached by means of theconnecting-rods 27 27 to the outer ends of a lever 28, centrally pivotedon the carriage 23. The rods 7 7 are also connected, respectively, tothe extremities of the lever 28. These steam-cylinders 25 25 aresupplied with steam from any convenient source, either the boiler of thelocomotive or a separate boiler'located on a car, through thesteam-induction pipes 29 29, entering the steam-chests 26 26, from whichthe steam is alternately admitted to the steam-cylinders 25 25 on oneside of the piston only, and discharged therefrom by means ofreciprocating cut-oft valves in the steam-chest operated by the stem andlever. (Seen at 30 30.) The interior mechanism of the steam-cylinder andthe steam-chest is not shown in detail, as such mechanism is in commonuse andA is well known among all mechanics. A steam-cylinder 3l issecured iixedly to the bottom of the car B within an aperture thereforin the carriage 23, which cylinder is provided with a piston having astem 32, the outer extremity of which stem is connected to the carriage23 and the steamcylinder is provided with a steam-induct-ionV pipe 33,leading from a steamsupply into it behind the piston,whereby when steamis let into the cylinder the piston will be forced forward carrying thecarriage 23 with it, and thereby taking up the slack in the chains 9 9,so that when the rods 7 7 are to be reciprocated by means of steamintroduced into the cylinders 25 25 the slack will be so taken up thatthe working of the pistons in the cylinders 25 25 will at once act onthe rods 7 7 and on the cases 2 2, tilting them forward. Theconnecting-rods 27 27 are pivoted at both ends to `provide for thecurvilinear motion of the oscillating lever 28,being pivoted at theirrear endswith the stems 27 27 in the traveling guide-blocks 34 34, whichare supported and travel in the ways 35 35, secured to the carriage 23.

Additional sets of ratchet-wheels with their allied mechanism may beattached to other axles of the car and connected through the cases withthe` reciprocating rods, if desired. It will be seen that the cases 2and 2 and 2 and 2a can be oscillated alternately without the chains 1616, and the lever l5, by the counterpoises S 8, being constructed ofsufiicient weight to .tilt the cases and the theretoattached mechanismrearwardly quickly on being released from the alternately-forward pullof the rods 7 and 7, respectively; but the double construction of thegravity-weights in connection with the chains 16 16 and lever 15 ispreferred.
